2 hints appearing when TextInputLayout is focused

Question

I am having some trouble with the TextInputLayout.

When the TextInputLayout is focused, I am seeing the hint text float above the text field and also stay on the text field. Attaching images:

And when I type stuff on the field, the text overlaps the hint on the text field.

This is the XML for my TextInputLayout

 <com.google.android.material.textfield.TextInputLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="32dp"
        app:layout_constraintTop_toBottomOf="@+id/imageView" app:layout_constraintEnd_toEndOf="parent"
        android:layout_marginEnd="32dp" app:layout_constraintStart_toStartOf="parent"
        android:layout_marginStart="32dp" android:id="@+id/email"
        android:hint="hint">

    <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

I am using the android material components library like so:

implementation 'com.google.android.material:material:1.0.0'

How do I get the hint TextInputLayout to hide when it is focused on has text on it?

Here is the complete layout:

Turns out I was just loading the fragment twice.

I was loading in the Fragment once using navigation components and a second time from the main activity auto-generated boilerplate code you get when you use an Activity + Fragment template.

To solve the issue, just remove the FragmentTrancaction.replace from your main activity and let the Nav Component load up the fragment for you.
